It's now just 4 weeks out from the 2016 Arnold Classic and things are heating up.

Brett takes competition seriously. Even though his football career was cut short by his diabetes diagnosis in college, he fills the void by competing on stage.

Now just 1 year after earning his IFBB pro card, Brett's gearing up for his biggest competitive challenge.

To make sure he's fueling his workouts for peak performance, he has a detailed supplementation plan.

Before heading to the gym, Brett chugs a quick pre-workout supplement. He also mixes up a protein shake with whey protein plus Karbolyn. He drinks about half of this pre-workout and finishes it after he's done.
